Equipment Classification: M - Construction Materials, Structural Items
Construction materials are the basic materials used to construct equipment and structures. Each type of material has tradeoffs for strength-to-weight ratio, stiffness, and cost. Most of the materials here are given weights and costs for 1 kg of material to allow better comparison of these values, even though many of them will be used in larger or smaller quantities.
Bio-plastic (also Bioplastic, bioplas or bioplaz) is a polymer created through the use of genetically engineered bacteria. The creation process of bio-plastic involves pouring a feedstock nutrient solution into a mold and adding the engineered bacteria. As the nutrients are consumed the bacteria produce plastics as a byproduct, which combine with the feedstock to produce the final results. When the nutrients are exhausted, the bacteria simply die off. The time required for the bacteria to finish their work depends upon the size of the mold. In general, it takes about an hour per liter to have the bio-plastic bacteria, longer for complex objects, less for larger or solid blocks.
Bio-plastic is cheap, easily moldable, and relatively quick way or producing a wide variety of goods. The density and composition of the plastic is easily varied from light weight foamed composites to high density solid members. The former used for packing materials and light weight containers, the latter for building materials. Colors can be added by the addition of dyes to the feedstock.
The only drawback to bio-plastic is its vulnerability to Ultraviolet light. The plastic degrades under constant exposure to UV, becoming unusable after a few weeks to a few months. It also does not work well under conditions of extreme environments (heat, cold or vacuum).
Bio-plastic is most frequently used as part of a colonization equipment list.
The most common form of shipping the Bio-plastic bacteria is in a 10-liter container, which weighs about 12 kg, and costs Cr20,000. The bacteria in shipment have been freeze-dried and can last several decades. Once revived by application of their nutrient feedstock, they are very vulnerable and can live only a few minutes when exposed to anything but their own sealed environment.
Bonded Superdense is a conventional material that has had its molecular structure partially collapsed in a massive artificial gravity field and the electron bonds artificially strengthened by both induced electrical current and use of the Nuclear Damper technology.
Carballoy is an alloy of carbon in a diamond matrix and several metals to form a lightweight material with great resistance to environmental corrosive effects.
Coherent Superdense is a armor/hull material formed dynamically manipulated by input from the sensors and the computer so as to polarize the subatomic forces in the hull molecules, thereby presenting maximum penetration resistance to the specific striking weapon.
Composite Laminate are matrices of different metallic and nonmetallic materials arranged to make the most of each material's strengths. Most composite armor are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armor stronger, lighter and less voluminous than traditional armor, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle.
The most common type of composite sandwiches a layer of ceramic between two plates of steel armour, which was shown to dramatically increase the resistance to high explosive anti-tank (HEAT) rounds. Other versions have glass reinforced plastic sandwiched between inner and outer steel layers. A boron carbide-filled resin aggregate provides greatly improved protection. Ceramic armour is significantly less effective against a kinetic energy penetrator, so sometimes depleted uranium layers are added to provide extra protection against these warheads.
Explosive reactive armour, uses layers of high explosive sandwiched between steel plates. When a shaped-charge warhead hits, the explosive detonates and pushes the steel plates into the warhead, disrupting the flow of the charge's liquid metal penetrator (usually copper at around 500 degrees; it can be made to flow like water by sufficiently immense pressure). It is less effective against kinetic penetrators.

Crystaliron is a ferrous armour hull plating used for protection on vehicles and ships. It utilizes metal with perfect crystal structure and carefully controlled impurities to gain maximum hardness and toughness.
Polylucent cuprothallium is a transparent material used in heads up displays and communications devices used for projecting data.
Cupro is a cellulose based fiber or fabric. Polylucent cuprothallium is cellulose doped with thallium (which is used in optics and electronics), used to make 3D displays.
It is a manufactured substance based around a copper-thallium alloy that emits low levels of EM energy across a broad spectrum when a power source is applied to it. The substance is inherently unstable. It is typically found as a molecular layer within a transparent veneer, such as a vacc suit visor, where it can be electrically induced to display data.
Daystone is a substance considerably harder than diamonds that has many important industrial applications. It is usually formed under the titanic pressures of worlds such as Diablo (Reaver's Deep 2423) or similar worlds.
Fiberglass is a common type of fiber-reinforced plastic using glass fiber. The plastic matrix may be epoxy, polyester resin or thermoplastic. The glass fibers may be randomly arranged, flattened into a sheet (called a chopped strand mat), or woven into a fabric
Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, is non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances.

Hazelhearth is a fine-grained, slow-growing tree. It is particularly prized for its carving qualities. However, due to its resinous nature, it is best left to dry for several decades.
Hellboria Wood has a grain pattern which alters slowly with time, even once the tree is dead. Combined with its blue striated appearance, Hellboria wood is considered attractive.
It is used in a wide range of designer products, from the racquet handles of zipwire star players, to luxury furniture.
Lightweight Composite Laminate
|Lightweight Composite Laminate|
Light composites at TL–7 represent a variety of additional non-metallic structural materials, such as graphite, boron-carbide, and so on.
Neivher is a synthetic substance know for its toughness as it can be fashioned into projectiles with the penetrating power of solid slugs. It is valued for its ability to dissolve harmlessly in the human (or other biologic) in five to ten minutes. Often used for tranq or poison in order to penetrate armor. Originally designed as body armor but its rapid decay when saturated with sweat or other body fluids made it impractical in that role.
Plascrete is a cheap, widely use building material. Mixed in about a 1:10 ratio with filler material such as sand or plastic pellets, it makes a slurry that hardens only when a high-frequency electrical discharge is passed through it, a process which takes about half an hour for a 500 kg block. Normally, an electrode gets painted at the bottom of the form, and another on the top, though other means of achieving the discharge are possible. The resulting plascrete is waterproof, airtight, and resistant to all known molds and micro-organisms. It has much better compressive than tensile strength and is only used as pressure walls if the pressure inside is less than that outside.
A variant of the plascrete is foamed plascrete and is the more widely used form. Nozzles and aerator blow an air-filled slurry of plascrete into a mold or onto a surface, and electrode connections harden the result almost instantaneously, but only a thin layer at a time. The benefits are that 75% less plascrete is used, it is self-insulating because of the air spaces, and it is much lighter than solid plascrete (it floats). In addition, vertical surfaces or inverted surfaces can be "plascrete-plated", making it useful to stabilize weakened structures. Additives are available to enhance or retain normal properties.
Plascrete is normally sold dry, in 250-liter drums.
Plasteel or plastisteel is a construction material, a composite of plastic resins and steel. Retains the lighter weight, elasticity, corrosion resistance of the plastics, but gains additional strength and heat resistance from the reinforcing steel. Most frequently found as a building material for smaller permanent structures and some vehicles exteriors. There are numerous grades of Plasteel depending upon exact design specifications.

Reinforced plascrete is an upgraded form of plascrete, with strips of superdense plascrete inside for greater strength. It is cheap and widely used enough, that many think of it as "a TL-12 version of plascrete" and just call it "plascrete".
Just as concrete has better compressive than tensile strength, so too does plascrete. One common TL-2 solution for concrete is to add reinforcing bars of metal into the concrete, but plascrete is strong enough that the same metal bars do not appreciably help. The development of superdense provides an equivalent solution.
Reinforced plascrete starts off as ordinary plascrete, though of a mixture that facilitates gravitational compression. After the plascrete is put in place and hardened via electric current, a strong but short range artificial gravity system is waved over the plascrete, partially collapsing the molecular structure in thin lines, typically in a grid pattern. Care must be taken to collapse along a gradient, rather than strongly crushing one section but leaving the immediate vicinity untouched, which would cause the collapsed section to crumble. As many construction instructors have put it, "make smooth valleys, not sharp canyons". Additional plascrete is then formed over the resulting troughs to make a smooth surface, and encase the superdense portions.
This method of reinforcement is not compatible with foamed plascrete, which remains more widely used than reinforced plascrete. Reinforced plascrete retains the waterproof, airtight, and micro-organism resistance qualities of plascrete. Compressing like this significantly enhances tensile strength at some cost to compressive strength; the optimal mix is about 11% compressed, the exact percentage depending on which additives are present in the plascrete. The result of this process should not be confused with superdense armor, which uses different ingredients as well as 100% compression instead of 11%. Reinforced plascrete is most commonly manufactured on a construction site from sand and aggregates, but plascrete suitable for reinforcement is also sold dry, most often in 250 liter drums (which, with 11% compression, becomes 225 liters of reinforced plascrete).
Resincrete is a weatherproof powder that combines with water to form a pliable building compound. Usable in almost any climate (will harden properly down to -40 celsius), Resincrete can be used to build shelters, barricades, & used as a cement with other building materials.
Shimmerstone is a type of stone, after having been exposed to the chemical oceans on Akimu (Dagudashaag 0106) gain a shimmering, iridescent quality that has made it popular as a building material. The iridescence gradually fades unless the rock is carefully prepared and the way the stone is 'fixed' is a closely guarded secret. Quarrying the correct stone, which only occurs on Akimu, is dangerous and time consuming and the exorbitant prices charged for the finished product reflect this. Nonetheless Shimmerstone is highly sought after for up-market building projects throughout the Domain.
Steel Foam is a very useful industrial product, often used in the construction industry. It was first developed by SuSAG's Industrial Chemicals Division in 670, and filled the need for a strong, fast setting construction material. It was later marketed by many other companies, but SuSAG still manufactures the highest quality foam.
Steel foam is a combination of chemicals which forms a foam when it comes in contact with oxygen. The foam then hardens quickly to form plasteel. Available in many sizes of container, it is most often sold in 9kg tanks, similar to fire extinguishers. The container holds enough chemical under pressure to form ten cubic meters of hardened foam.
Users can spray about one cubic meter of Steel foam five seconds. The foam takes another minute for it to expand and dry. When set it is very strong and resembles cement. It used by troops to quickly erect shields and bunkers by spraying it over an inflated mold. It is used on starships to temporarily seal breaches in the hull, and in many high-tech structures as emergency fire barriers.
Structurecomp or Structural composite is a generic term for a medium quality structural material with the properties needed for many civilian applications. It is usually a honeycombed or foamed core of metal and/or ceramics, spray-faced with synthetic fibers to provide an extremely high tensile strength on both sides, with corresponding stiffness. The outer face is then sprayed or dipped with a similar fiber matrix in a smooth carrier to provide a mirror-like finish. For applications like vehicle bodies, all layers are dyed the same color if possible, to minimize the visual effect of scratches or other minor damage. The resulting product is stiff, light, and has good energy absorbing abilities. Structural members may also be made in the same fashion, but without the attention to coloration.
Superdense is a structural material usually used for armor on advanced military vehicles. Superdense is a conventional material that has had its molecular structure partially collapsed in a massive artificial gravity field, which increases its density and strength.
Synthetic Diamond is mass-produced slabs carbon in a diamond crystal, a useful industrial good in TL–6 to TL–9 cultures which cannot produce it themselves Basic 1 m x 2 cm x 10 cm slabs cost about Cr100 in bulk and mass 200 kg each. The most common applications are research and industrial, such as windows in high-performance aircraft or deep-diving submersibles, wind tunnel monitoring ports or high-refraction lenses for astronomical use.
Synthetic diamond in large and/or curved areas is only commercially possible with fusion power and contragrav technology, and is not economical until TL–11. It is the material of choice for transparency, toughness, and scratch resistance. Prior to its development, such applications required synthetic quartz, which is technologically less sophisticated, but also not as capable and prohibitively expensive for most applications.
Its limitation as a structural material is its brittleness: it breaks rather than bends, and any weapon may cause severe cracking over a large area, regardless of its thickness.
Its transparency can be adjusted to darken (near instantaneously) in response to sudden brightness; in dark mode, the material is opaque. Transpex is suitable as a display screen or media on which are overlayed infographics, communications, images, and instrument displays.
Transpex is inferior to hullmetal or hull armor. A typical installation includes external shutters that provide suitable armor protection.
